How to Kiss

The Kiss - technical explanation: Kissing is a complex
behavior that requires significant muscular coordination; in fact, a
total of twenty muscles working cooperatively. The most important muscle
involved is the orbicularis oris muscle, which is used to pucker the
lips and informally known as the kissing muscle. The tongue can also be
an important part of the kiss.

The Kiss - affection explanation: As an expression of
romantic affection or sexual desire, kissing involves two people kissing
one another on the lips, usually with much more intensity, and for a
considerably longer period of time. In more passionate kissing couples
may open their mouths, suck on each other's lips, or move their tongues
into each others' mouths (see French kiss). Sexual kissing may also
involve one person kissing another on various parts of the body.
